TYPEWRITER ATTAcHMnNT.

To all whom it may concern:

Be it known that I, WILLIAM D. REID, a citizen of the United States, anda resident of the city of New York, borough of Brooklyn, county ofKings, and State of New York, have invented a new and useful TypewriterAttachment, of which the description. I

It is well appreciated that considerable diificulty is experienced inconnection with typewriting machines in that the ribbon disintegrates,resulting in small particles thereof becoming lodged in-the face of thetype, which causes a gradual clogging up of the spaces partially orcompletely inclosed by the type, as, "for instance, the letters 0, P, D,etc. i

It has been customary to provide a small hand brush with a view ofpermitting the typist to clean the face of the type. This results in thewasting of considerable time asidefrom soiling thehands of the operator.-It has been pro osed, with a view of eliminating this di culty, toprovide a removable brush which might be associated ainst the face ofsuch brush the type w ic has be-. come clogged. The feasibility of? thissuggestion will readily be appreciated in that it is only necessary fora typist to apply the brush to the type guide and to sharply depress thekeys, operating the type to be cleaned, this operation being rapid andnot soiling the fingers of the typist.

This latter type of brush as placed upon the market, however, has beenrather exuse, v1z., that of cleaning the face of the type.

My invention now contemplates the pro vision of a brush which may beassociated with the type guide, and which is very unlikely to becomeaccidentally removed therefrom, and by means of which the face of thetype is insured of a thorough cleaning.

Further objects of my invention are the construction of a device of thisnature which shall not be limited to this one purpose, and which shallbe capable of construction at an extremely low figure so as to becommercially practical. a

- Reference is-had to the attached sheet of drawings which practicallyillustrates one Specification of Letters Patent.

-- ment;

is also only capable of one practical embodiment of my invention, and inwhich:

Figure 1 is a partly sectional side view through a typewriter having myimproved attachment associated therewith;

Fig. 2-is a plan view thereof;

Fig. 3 is a rear face view of my attach- Fig. 4 is a sectional side viewthereof, taken along lines 4t of Fig. 3, and,

Fig. 5 is a perspective view of a certain detail of the inventionhereinafter more particularly referred to.

In all of these VIGWS like reference nu- Inerals designate similarparts, and 1 indicates the platen of a typewriter, in front of whichthere is positioned in the usual manner the type guide 2 formed with aslot into which keys 3 carrying the type may be projected.

I now construct my typewriter attachment so that the same' includes aneraser 4: of conventional construction ber 5. Through this shield 5thereare formed openings 6, preferably square, openings being cutthrough the eraser in alinement with the openings 6, as has been clearlyshown at7, of"smaller diameter than ed to inclose the bristles 8 and isretained in applied position by any suitable construction, such as forinstance, tending prongs having associated, with it a finger shield andstiffening mem-.

openings formed in the body of the eraser 4.

It will now-be appreciated that the cap 10 may readily be removed fromthe face of the eraser 41, and that the latter may be readily associatedwith the type guide 2 by pushing the eraser upon such type guide so thatthe arms of the same project through the openings 6 and 7, thelatter'giving frictional engagement with the arms of the type guide sothat any danger of accidental removal of the eraser is eliminated; Thekeys corresponding to such type as is to be cleaned may now be depressedand the same will have any particles lodged in their faces removed byvirtue of the contact be- The cap 10 may now be associated with theeraser 4 by mere depression, pressing diametrically opposite points inline with the prongs 11, so that these prongs may be inserted into theircorresponding openings in the eraser 4. The eraser may now be withdrawn,or, if it is desired, maybe removed from the type guide prior to the application of the cap 10, and by virtue of this ca the fingers of thetypist will not be soiled and my attachment may be utilized as aneraser.

Obviously any number of modifications might be resorted to withoutdeparting from the spirit of my invention, as embodied in the scopeof'the attached claims which read:

LA typewriter attachment comprising in combination, an eraser presentinga pair of side faces and bristles associated with one of the faces ofsuch eraser, and extend ing outwardly therefrom.

2. A typewriter attachment, comprising an eraser capable of beingassociated with a type-guide, and means attached to said eraser forpermitting of a cleansing of type, upon an actuation of the samesubsequent to the association of said eraser with said type uide.

3. typewriter attachment including, in combination a member comprising abody portion adapted to be associated with the type-guide, and meansattached to said body portion for permitting a cleansing of the typeupon their actuation, subsequent to the attachment of the body portionwith tlu type guide.

4. An eraser, comprising a body portion presenting a pair of side faces,bristles attached to one of said side faces and extending outwardlytherefrom, said body portion being formed with openings through whichthe prongs of a type-guide may project to permit of the attachment ofsaid eraser to a typewriter.

5. A typewriter attachment including in combination, an eraser, a shieldassociated with such eraser, means forming a part of such eraser forpermitting an attachment, of the same to a type guide, a backing plateassociated with the shield of said eraser, and bristles attached to saidbacking plate.

6. A typewriter attachment including in combination, an eraser, a shieldassociated with such eraser, means forming a part of such eraser forpermitting an attachment of the same to a type guide, a backing plateassociated with the shield of said eraser, bristles attached to saidbacking plate, and a cap adapted to envelop said bristles and beingremovably associated with said eraser.

7. An eraser, including a body portion formed with a plurality ofopenings and plates arranged upon the faces of said body portion andbeing also formed with a plurality of openings adapted to aline with theopenings through the body portion of said 8. An eraser, including a bodyportion formed with openings and plates arranged upon the faces of saidbody portion and being also formed with openings adapted to aline withthe openings through the body portion of said eraser, the openingsthrough said plates being of a larger diameter than the openings throughthe body portion of the eraser.

9. In combination, an eraser including a body portion presenting a pairof side faces, bristles attached to and extending from one of said sidefaces, an enveloping-cap for said bristles, said cap being formed withprongs adapted to project into the openings formed in one of the sidefaces of said body portion.
